“Hello everybody. I’m just sitting in the back of the car with Jason and my second child,” Mollen, 38, said in the first of a series of clips shared on Instagram Stories Thursday, showing herself and Biggs in a car with their newborn son.

Addressing her husband after panning the camera to their new little guy, situated between his parents in his car seat, Mollen says, “Baby, you have two boys now.”

“I had to break out of the hospital, they wanted to keep me, but I’m leaving — I’m leaving with wires attached,” Mollen adds. Biggs replies jokingly, “Was I supposed to sign [discharge] papers or pay or anything?”

Shortly after, Mollen posted a video to Instagram of herself in a hospital bed, gazing at a golden pineapple-shaped ur on a chair. “Obviously had to bring Teets for moral support…. #babybiggs,” she wrote, referring to her beloved dog who died in March 2016.

“It actually hasn’t been a big deal so far because I’m so early,” Mollen told PEOPLE in June. “I had a c-section the first time because I never dilated, so I’m not that concerned because I expected to have to be cut open again.”

At the time, Biggs explained that Sid wasn’t quite sure what was in store for him with a new sibling on the way. “While it’s still safely tucked away and he doesn’t have to actually physically deal with someone else in his space, he loves it,” the Orange Is the New Blackstar told PEOPLE.

Placenta previa and juggling a toddler and impending second-time motherhood aren’t the only challenges Mollen faced throughout her pregnancy. In early September, the Angel alum shared her experience with what she described as “prepartum” depression in an Instagram post and Story.

“I could already be in a depression,” she revealed. “I’m planning on eating my placenta, but I’m also anticipating a major emotional dive. I think that it’s chemical. I think people don’t talk about it enough.”

The following day, Mollen clarified that she was “totally fine” after receiving an influx of concerned emails. “This is normal — that’s what I’m trying to say,” she explained. “That it’s not weird … I would be more freaked out if I weren’t freaking out.”

Over the past six months, Mollen has been extremely open about her changing body, posting a variety of nude mirror selfies and joking, “Can I keep the boobs?” in the caption of one recent before-and-after shot.
